Metadata Monday: Microdata and Schema.org

Don't we all need another standard or schema for web page markup? Fear not, the folks at Google, Bing and Yahoo! have collaborated on Schema.org - "to improve the web by creating a structured data markup schema supported by major search engines. On-page markup helps search engines understand the information on web pages and provide richer search results. A shared markup vocabulary makes easier for webmasters to decide on a markup schema and get the maximum benefit for their efforts.

Schema.org provides a collection of shared vocabularies webmasters can use to mark up their pages in ways that can be understood by the major search engines: Google, Microsoft, and Yahoo!

You use the schema.org vocabulary, along with the microdata format, to add information to your HTML content. While the long term goal is to support a wider range of formats,
the initial focus is on Microdata. This guide will help get you up to speed with microdata and schema.org, so that you can start adding markup to your web pages."

To me, this schema, based on RDF, is akin in simplicity to Dublin Core and a boon to those wishing to ensure their content is understood by those sometimes obtuse search engines.
